Description

Forming equipment and process of lining mold Technical Field The invention relates to the technical field of production of lining molds, in particular to a molding device and a molding process of a lining mold. Background The ceramic tableware is produced with clay, feldspar, quartz and other inorganic non-metal mineral as material and through compounding, crushing, forming, sintering and other technological steps. With the technical progress, ceramic products with complex shapes and high precision requirements are increasingly popular, and ceramic powder is adopted for forming by an isostatic pressing technology. Isostatic compaction techniques utilize a fluid medium (e.g., liquid or gas) to uniformly apply pressure to ceramic powder encapsulated in a flexible mold (typically a gum liner mold) to densify the powder particles and form a uniform high density greenbody. The blank formed by the method has the advantages of uniform density, few defects, high strength and the like, and is particularly suitable for manufacturing ceramic tableware with equiaxial symmetry or complex structure of discs and bowls. In the isostatic pressing process, the gum cover type lining mold is a key tool, and is usually formed by injecting liquid polyurethane (such as pouring polyurethane elastomer) into a specific combined mold and heating and curing. The properties (e.g., elasticity, strength, durability) and dimensional accuracy of such lining molds directly affect the quality of the subsequent ceramic powder compacts. However, existing lining mold forming processes typically consist of three parts, namely an upper mold, a middle mold and a lower mold, which are separable. After injection molding, the three parts are separated manually, and the molded lining rubber sleeve is taken out of the middle mold.
